Question

Quizplus · Accepted Answer

Public key encryption uses a pair of keys: a public key for encryption and a private key for decryption. The public key can be shared openly without compromising the security of the encrypted messages, as only the private key can decrypt them. This means that even if an unauthorized party obtains the public key, they cannot decrypt messages encrypted with it, making the system secure even if the encryption key (public key) is known to potential attackers.
